/*
    Group Sofware Serial Bridge LED code
    Crosses RX and TX compared to nodes.
    Starts by resetting all IDS by sending 0.
    Sends the ID over the serial port, waits two seconds, second the second ID.
    This code is based on the work of Cody Bradly at http://www.ernstc.dk/arduino/tinycom.html
    and on the SoftwareSerialExample Tom Igoe
